Solar Water Pumping
Limiting Flow on AC voltage - Grundfos 11 SQF 2 pump
Maybe I'm missing something, but it seems to me a level sensor or float switch in the well is the simplest solution. It would just open a relay on the AC generator output when the water level gets too low?
Main daytime system ~4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformer
Night system ~1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter
I am missing it also.... Just add more panels and tanks and use a float switch. This is what everyone does who does not like remote genset runs.
